I own a 1999 Mustang Gt. I have two new Dunlop tires in the rear and two slightly used Hankook tires in the front. They've been good since I've had the car for 3 months and up to this point I haven't experienced anything effecting my driving. I was driving on the highway at speeds of 65 M.P.H., when I came around a bend and then all of a sudden I heard a pop of some kind around my front right tire and after examination I didn't notice any damage to the tire. As I pull off an annoying clicking sound starts coming from my front right tire and I keep driving. I drove 7 miles towards my school with this annoying sound and I didn't think anything of it. Suddenly as I returned home the clicking intensified and transformed into a dull thud noise and my steering wheel started vibrating. I told my passenger to look out and he exclaimed that the tire was wobbling and I felt it as well. It got worse and I didn't know what to do. I just drove slowly home and have been researching what could it be since then. It sounds like something having to do with the front axle or the bearings but I'm no expert. Can anyone with expertise give me some input and help me out with quotes so my mechanic doesn't overprice me. I'm a struggling student and can't afford to have a broken car since I commute as well as I can't afford to overpay. Thank you
